A series of lanthanide complexes with general formula [Ln(NTA)(3)X] were prapared [Ln = Y (a), Er (b), Eu (c), NTA = naphthoyltrifluoroacetone, X = H2O (1), phen = phenanthroline (2), bpyO1 = 2,2'-bipyridine N-oxide (3), and bpyO2 = 2,2'-bipyridine-N,N'-dioxide (4)]. The crystal structures of [Eu(NTA)(3)bpyO2] (4b), [Er(NTA)(3)bpyO1] (3c), and [Er(NTA)(3)phen] (2c) were determined. X-ray crystallographic analysis reveals that the complexes are of mononuclear structure with three NTA and one ancillary ligand. The photoluminescence spectra of 3c and 4b exhibit strong characteristic emissions arising from Eu3+ central ion due to the efficient sensitization of bpyO1 and bpyO2, respectively.
